10 signs you need to replace your HP laptop battery
💡 Need to know
- Fast battery drain doesn't always mean battery failure. Performance settings, heat, and background apps can also reduce battery life.
- Swelling is different. If the battery looks bloated, stop using the laptop until it's inspected.
- Check battery health before buying parts. HP and Windows both offer tools that can help confirm the problem.
- Most batteries wear out gradually. The warning signs usually show up long before the battery completely fails.
You're typing away on your HP® laptop when you notice your battery is draining fast. Come to think of it, your computer has been taking a long time to charge. You may need a new battery. But how do you know for sure? We'll share our expert advice.
At Asurion, we help take care of your favorite tech, whether you want to speed up a slow laptop or get the most out of your tech when you travel. Here's our guide to replacing your HP laptop battery.
Signs your HP laptop needs a new battery
Most laptop batteries are good for at least a few years—but they don't last forever. When a battery is dying, your device will give you clues, including:
- Your laptop takes a long time to charge or won't charge at all.
- Your laptop battery dies sooner than it used to.
- Your laptop only works when it's plugged in.
- Your laptop battery looks bloated.
- Your laptop overheats.
- Your device displays a battery replacement alert.
- Your laptop shuts down unexpectedly
- Your laptop experiences a decline in speed
- Your laptop suddenly doesn’t detect the battery
- Your laptop battery percentage fluctuates unpredictably or shows incorrect readings
Check battery health before replacing it
Before ordering a replacement battery, it's worth confirming that the battery is actually the drama. Windows includes a built-in battery report tool that can help you measure battery wear.
- Open Command Prompt or Terminal.
- Type: powercfg /batteryreport
- Press Enter.
- Open the generated report.
Compare the battery's Design Capacity to its Full Charge Capacity. If the current capacity is significantly lower than the original design capacity, the battery has likely worn down over time.
Should you replace your HP laptop battery yourself?
If you think you need a new HP laptop battery, keep in mind that replacing it yourself can be challenging.
Accessing the battery on many HP laptop models requires opening the laptop and removing internal components. If you're not experienced with laptop repairs, you could damage your device. Depending on the model and warranty status, opening the laptop may also affect warranty coverage.

But first... back up your data
Before replacing your battery—or getting a repair expert to do it for you—make sure you back up your personal files. Your important data—including photos, videos, and messages—could be lost during the replacement process.
Ways to extend the life of your HP laptop battery
Got a new battery? The next step is to take good care of it. Here's how to extend the life of your HP laptop battery.
Keep your HP laptop cool
Heat—and especially direct sunlight—can accelerate battery wear. Charge and use your laptop in a cool, well-ventilated area whenever possible.
Check your charging cable
Inspect your charging cable regularly for signs of wear or damage. Whenever possible, use the charger designed for your laptop model. Poor-quality chargers can cause charging issues and may affect battery performance.
Adjust your screen brightness
Reducing screen brightness is one of the easiest ways to extend battery life. Use your laptop's brightness controls to lower the screen when full brightness isn't necessary.
Unplug accessories you don't need
External devices such as USB drives, headphones, and other peripherals draw power from your laptop. Disconnect accessories when you're not actively using them.
Close apps and programs you're not using
Background applications consume power even when you're not actively using them. Closing unnecessary programs can help improve battery life and overall performance.
Use battery-health features when available
Many modern HP laptops include battery-health and adaptive-charging features designed to reduce long-term battery wear.
If your model offers these tools, consider enabling them and letting the system manage charging behavior automatically.
Restart your laptop occasionally
Restarting your laptop periodically can help clear temporary software issues and keep the system running smoothly.
Update your operating system
An outdated operating system can sometimes affect battery performance. To check for updates:
- Select Start > Settings > Update & Security.
- Open the Windows Update tab.
- Select Check for updates.
If updates are available, Windows will download and install them automatically.
Use your laptop's built-in battery tools
Windows includes built-in power-management tools that can help identify apps and settings that use the most battery power.
- Windows 10: Select the battery icon on the taskbar and adjust the power slider.
- Windows 11: Go to Settings > System > Power & Battery > Power Mode.
If your HP laptop includes settings such as Optimized Battery Charging or similar battery-health features, turning them on may help reduce long-term battery wear.
If you've tried these steps and still need a little help, we're right around the corner. Schedule a repair at the nearest uBreakiFix® by Asurion store and our certified experts can get your device back up and running as soon as the same day.
